Definitions

• the invention concerns a lid for batteries which can be indifferently used on batteries of the "KAMINA” type or on the so-called “ re-combination” type.
• the batteries of the "KAMINA” type are batteries realized according to the instructions given in the patent belonging to the German Company MOLL GMBH. These batteries are used in special environmental contexts, e.g. where it is advisable to prevent the fumes developed during the battery performance from being discharged in the environment wherein the batteries operate. It is for this reason that the batteries of the "KAMINA” type present a lid having in its interior a gas-conveying channel, which setting each one of the battery elements into communication with the others.
• the channel presents at least one hole on the rim of the battery lid on which a tube is attached which has the task of collecting and exhausting the fumes developed in the interior of the elements during the battery performance or during its recharging.
• the channel connecting each element is preferably realized in correspondence of the middle line of the alignment of the refilling holes of each element.
• Each cap inserted in said holes presents on its cylindrical wall at least one hole for communicating with the conveying channel, thus assuring the connection between adjacent sections of the channel. Therefore, it is easy to understand, that the fumes developed on each element pass through the holes of each cap of the battery element, and, through said holes, they reach the collector channel which then conveys the fumes, such as hydrogen, to the external environment, through one or two tubes connected at the end of said channel.
• the lid of the "re-combination” batteries presents a seal being hermetical in relation to the container and to its elements, with the only the one-way valves for the exhaust of possible inter- nal overpressures, as already mentioned.
• the present technigue foresees two different lids for the battery containers, one used for the batteries of the "KAMINA” type, foreseeing the exhaust of the fumes into the external environment through the collector tube, the other lid for the batteries of the "re-combination” type, having reguirements of hermetic seal and exhaust valves.
• the purpose of the invention is to obtain a lid for batteries realized in a single-molding piece which can be advantageously used both to produce the mentioned batteries of the "KAMINA” type and to produce the "re-combination” batteries. Therefore the intended purpose is to obtain two lids having different final characteristics beginning from the standard mold itself, the final articles being differentiated by adding other elements in order to make the lids compatible with the two different types of batteries.
• the lid accor- ding to the invention which, in accordance with the con- tent of the main claim comprises: - an essentially flat surface provided with a rim suited to be connected to the box of the container of the battery by means of welding or gluing; - a series of holes, aligned in relation to one another, each of them communicating with each element of the batte- ry; - a plurality of caps, each lodging in each of said holes and each of them having at least one hole suited to set into communication contiguous sections of a channel for the conveyance of the fumes generated in the battery; - at least one channel for conveying the' fumes generated by the battery, being realized under the external surface of the lid, setting into communication each element of the battery and having its ends facing the external surface of the lid, characterized in that at least one end of said at least one channel is closed by a one-way valve which lets out the fumes accumulated in the interior of
• the pla- stic manufact realized in one single mold it is possible to obtain that when it is necessary to produce a battery having the right requirements for collecting the fumes produced during the performance or the recharging and then conveying the same to the external environment through a tube, it suffices to connect at least one tube with one end of the channel present in the lid of the battery, the other end being provided with a cap when is not connected with the conveyance tube, while all the sealing caps of the refilling holes of the battery are such as to assure a good sealing, obtained, for instance, with conic surfaces for the coupling between the cap and the hole opening.
• the ends of the channel protruding from the rim of the lid will be closed with at least one one-way valve, consisting of a cap made of flexible plastic material or rubber, for instance, the other end of the channel being closed ' by means of caps.
• the sealing caps of the refilling holes no more needed now, will be sealed through sealing means present under the head of each cap, such as OR rings or similar.
• the lid according to the invention preferably moulded in polypro- pylene and indicated as a whole with 1, presents two holes for the passage of the poles, indicated with 2 and 3, and a further series of aligned holes 4, being in the same number as the number of the elements constituting the battery, which in the case of the example are six.
• the lid 1 presents in its lower part a conveyance channel 5 passing through the middle of the alignment of the holes 4 and arranged under the surface 6 of the lid 1.
• the ends of the channel 5, indicated with 7 and 8 in Fig. 2 are connected with a tube 9 with regard to the end 7, and closed by a cap 10 with regard to the end 8, as in the case of the example.
• Each hole 4 is supplied with a cap 11 presenting two holes 12 and 13 being in a diametrically opposed position, such as to insure the passage of the fumes coming from each element, indicated with 14, into the collecting channel 5, so that the fumes developed by each element 14 can be conveyed to the exterior through the exhaust tube 9.
• each hole 4 presents in its upper part an enlarged section 15 suited to house the head of the cap 11.
• the bottom of such enlarged mouth presents a flat annular part and an annular projection 16 having an essentially triangular profile. In this way said profile 16 realizes at one end a truncated-conic mouth for the cap which has under its head an equivalent shape so that during the screwing of the cap into the hole an essentially hermetic seal is obtained.
• the annular projection 16 defines the housing for an OR ring.
• the lid now described and represented in Fig. 2 is a lid essentially suitable for batteries of the "KAMINA" type. With regard instead to the assembly of lids suited to be arranged on batteries of the "re-combination” type, it can be observed that the seal necessary for obtaining an her e- tic sealing in relation to the exterior is realized by inserting an OR ring 17 under each head of each hole 11 and positioning it between the flat part of the bottom 15 and the annular projection 16. In this way, when the lid 11 is screwed into the housing of the hole 4, the OR ring is squeezed in, thus obtaining the hermetic sealing of the holes.
